Elongated cup-shaped spare by a lid (not shown) sealing with single opening, is provided with focal plane window 5 at the top in this opening.Elongated cup-shaped spare need be fixed on the fabric support of loom, is positioned to adhere on lid and the focal plane the window 5 and fabric that is woven that moves below.Although for example-not explanation-device according to the present invention is installed in the indicated position of arrow F among Fig. 5 in the drawings.
Therefore, the part of the fabric that above window 5, moves, if suitably illuminated, the sensing element 2 that can be set at illustrated optical path opposite end among Fig. 3 obtains.For this purpose, further provide lighting device, it and focal plane P
fCorrespondence has suitably illuminated fabric.
Preferably, lighting device is arranged in the elongated cup-shaped spare 1 (promptly below fabric), thus their feasible images that can obtain fabric by reflection.This lighting device for example is made up of one group eight LED (light emitting diode) 6, and they are fixed on a framework 7 that is arranged in window 5 belows and minute surface 4 tops.
For example the LED light emitting diode can be the Kingbright that emits white light
_The L54PWW type.
The LED light emitting diode preferably so is configured to make them can assemble (for example Fig. 3) mutually and is determined focal plane P
fOn the highest intensity of illumination.
By minute surface 4 half-twists and pass set of lenses 3 and longitudinally point to elongated cup-shaped spare 1, set of lenses makes on its sensing element that focuses on plate 2 by the fabric beam reflected.
Sensing element 2 be the CCD type and be suitable for obtaining light beam with default sampling interval, and with its conversion one with a kind of itself known mode-become analog signal or digit preference signal.
Sensing element 2 can be a two-dimensional array or, be preferably a linear array: in the latter case, the various image lines of scanning in time form a rectangular matrix, and the latter is suitable for by the appropriate mathematical algorithm process then so that the information that acquisition needs is as mentioned below.
The plate that has sensing element 2 is connected to a stacked printed circuit 8 by conductor 2a then, described printed circuit level is housed in the top of elongated cup-shaped spare 1, and it comprises that one is suitable for handling output signal and the confession circuit diagram of the data signal handled of microprocessor (not shown) subsequently being provided by CCD.Preferably, conductor 2a length fix-for example the plate with the form of the conventional pin that is used for microchip-have thus sensing element 2 is connected by fastened to each other with printed circuit 8.
According to a preferred embodiment of the invention, elongated cup-shaped spare 1 comprises contiguous block 1a, 1b and 1c at the relative transverse side of inside, and they are provided for the fixedly device of the described parts of preamble.
Particularly, intermediate mass 1b comprises the slit (not shown) that several are vertical: the plate that therefore has a sensing element 2 has permission and inserts thickness in these slits with its lateral edges.So just can insert described plate from the top, it is slipped in two selected relative slits, and pass through to use the top cover of elongated cup-shaped spare 1 with therein with its retaining.
Similarly, two other piece 1a and 1c comprise the screwed hole of one group of alignment, will be screwed into trip bolt in it with fixing stacked printed circuit 8.
This installation method make movable plate easily-and therefore sensing element 2 be suitable for obtaining image-enter in several predeterminated positions in the elongated cup-shaped spare 1 with its printed circuit, and thereby make focal length adapt to current situation.
Similarly, the set of lenses 3 of installing with cylindrical arrangement be placed on 1 one-tenth integrally formed bottom mounting 3a of cup-shaped spare on, set of lenses can be blocked by a top clamp 3b who is suitable for being screwed on the mounting 3a diverse location thereon.Configuration thus, set of lenses 3 can be fixed on the different lengthwise positions along cup-shaped spare 1 equally, to regulate optical path according to present case.
The possibility of these adjustings not only allows correct focusing to be placed on textile image on the window 5, also can revise magnification ratio (" amplification " function), so that also can in the image that obtains by sensing element, comprise the warp thread and the weft yarn of the desired amt that is woven fabric according to the change of textile design.
If expectation, when article change at every turn on loom, therefore might open the lid of container 1, with move have sensing element 2 plate (with printed circuit 8) in the slit of needs, move the optical path length of (perhaps even reject) set of lenses 3-obtain thus expectation-close the once more at last lid of elongated cup-shaped spare 1.
In the operation, along with the time can be used to different purposes by the image that device according to the present invention obtains.A particularly advantageous application of these images is the quality controls that are used for woven product.
The method that is used for described quality control provides the various digital pictures obtained along with the time comparing mutually, or and sample image relatively so that determine to be suitable for to show the statistical function of the index of fabric quality then.If described function is different with default design parameter, can send a warning or loom stop signal, it requires the operator to check problem whether to have occurred in the process of weaving.
Similarly, the numeral of image relatively makes to obtain and is adapted at the real-time condition curve that shows on the suitable display screen: by checking how according to the loom running parameter (for example described condition curve, the speed of main motor, velocity rate between withdrawal roller and the work beam or the like) variation and changing, the operator can set up the optimum weaving condition at certain products.
Other method can be used for handling the data by providing according to apparatus of the present invention, but thinks that it is inappropriate at this they being described in detail, because any further inventive content can form the theme of an independent patent application in these methods.
Reached previously described purpose fully according to device of the present invention, it can not hinder on other any fabric supports that are installed in loom with weaving element and, simultaneously, its makes the image that can obtain fabric portions when fabric knitting.
According to a preferred embodiment, illuminate the LED6 of the system of fabric-for example-comprise an interrupted job at intermittence, preferably have one according to the loom running parameter by the operator adjustable or automatic frequency.
Advantageously, the main motion homophase of the vibration of light radiation and loom.
This stroboscopic effect allows to obtain/take a sample to check the textile image that improves quality, that is, moving of the fabric on focal plane window 5 can not cause fuzzy or inaccuracy.In other words, by suitably selecting the operating frequency of illuminator, can eliminate the negative effect of trembling the image that obtains being caused of fabric.
